Abstract: Methods and compositions improve amino and fatty acids availability, for example by achieving better blood enrichment in limiting amino acids, such as arginine and lysine, and essential fatty acids, such as linoleic acid. A higher fat digestibility was observed when rendered meat meal in pet food was replaced with a fresh or frozen meat slurry. A slurry can be made by subjecting fresh or frozen meat to size reduction, cooking with direct steam injection to increase the moisture of the meat, and emulsification of the steam-injected meat; and the slurry can be added to a dry blend comprising one or more of meat meals, grains, vegetable proteins, fiber, vitamins, minerals or fats in a preconditioner. The mixture formed by adding the slurry to the dry blend can be extrusion-cooked, cut into pieces, and dried to form a dry pet food kibbles.

Abstract: The invention provides novel food compositions having a realistic meat-like appearance and texture. The compositions comprise from about 50 to about 98% functional proteins, from about 0.05 to about 2% of one or more cross-linking agents, and from about 2 to about 50% of one or more humectant plasticizers. The compositions are produced by heating a preconditioned mixture of the food components under pressure and then expanding the heated composition to form the food composition.
